Premarital Screening in Pakistan

Stay for the one test mistake that could hide a carrier result.

Why thalassemia comes first

Here's the thing: thalassemia is inherited, and carriers usually feel completely fine. You'd never know unless you test. But if both partners carry the beta thalassemia gene, every pregnancy has a one in four chance of a child with thalassemia major. A 2022 review says the trait is common in Pakistan, so doctors put this test first. Knowing before nikah gives you time to plan.

Chance if both parents are carriers

Now, this is where it gets interesting. If both of you carry the beta thalassemia gene, each pregnancy has a one in four chance of a child with thalassemia major. That's not a one-time roll of the dice, it's the same odds every single pregnancy. Having one healthy child doesn't lower the chance for the next. That's why knowing before nikah matters.

How the tests work

The first test is a simple blood count, or CBC. If you're a carrier, your red cells are small and pale, with a low MCV and MCH, even though your haemoglobin looks normal. But here's the catch: iron deficiency can look exactly the same. That's why the next test matters: Hb electrophoresis or HPLC, which separates your haemoglobin types. A raised HbA2 is the classic sign of beta thalassemia trait. Labs sometimes ask for ferritin too.

Same lab, same week

Here's a practical tip: ask both partners to give samples at the same accredited lab, same week. Don't just ask for a CBC alone, request electrophoresis or HPLC directly. Ask for printed reports with the lab's reference ranges. Two reports from one lab are much easier for a doctor to compare. And doing it early keeps the result a private conversation between the two of you, before relatives start sending sweets.

Both carriers: what now?

If both of you are carriers, take a breath, have a chai, and then go see a haematologist or a genetic counsellor before pregnancy. A carrier result is not a reason to panic, and it's not by itself a reason to cancel anything. Couples discuss options: prenatal diagnosis, testing early to see if the baby is affected, IVF with embryo testing, which is costly and not for everyone, and some families choose not to marry, and that's their right too.

A carrier result is information

A carrier result is information, not a verdict on a match. That's the line to hold onto. It doesn't say anything about who you are or how much you love each other. It just tells you something you can work with. And working with it, with the right doctors, is exactly what it's for. Think about it: information is power, especially when it comes before a decision.

Why hepatitis B, C, HIV

What surprised me is how many couples skip these tests. These three infections often cause no symptoms for years, spread through blood and sexual contact, and can pass to a baby. Finding out before marriage changes everything. Test negative for hepatitis B? You can get vaccinated before marriage. Hepatitis C? Modern treatment can often clear the virus, so a positive anti-HCV leads to a PCR test. And HIV? Treatment protects your health and hugely reduces the chance of passing it to a partner or baby.

Blood group and the extras

Now blood group. It matters mainly for pregnancy. If you're Rh negative and your partner is Rh positive, the antenatal team will monitor and protect you at the right times. It's not a reason to avoid marriage. Some packages add sugar, thyroid, rubella immunity, syphilis, even semen analysis. Rubella immunity is worth checking for women, since vaccination should happen before pregnancy, not during it.

Is it required by law?

Here's the legal picture: rules differ by province and they've changed over time. The 2022 review notes that legislation for premarital thalassemia screening was approved in Sindh, Khyber Pakhtunkhwa, and Balochistan, but implementation remains the problem. So check the current requirement with your nikah registrar or local health department. Whatever the law says, testing is worth doing for your own planning.

Privacy and family pressure

Results are private. They belong to the person tested, not to anyone else. Share them between the couple first, and with families only if both of you agree, even if nani means well. And if a hepatitis or HIV result comes back positive, discuss it with a doctor before anyone else, so the facts come before the gossip. This is your life, your health, and your marriage. You get to decide who knows what and when.

The one mistake to avoid

Now, the part most people miss. A single CBC cannot rule out thalassemia trait, and iron deficiency can hide it. So if you only do a blood count, you might walk away thinking you're fine when you're really a carrier. Insist on electrophoresis or HPLC. Alpha thalassemia isn't always picked up either, so if there's a family history, you may need DNA testing. And a reactive hepatitis or HIV screen needs a confirmatory test.
