How to Store Lab Reagents in Ghana: 7 Practical Tips
Learning how to store lab reagents is one of the cheapest ways to protect both your results and your budget. A reagent that sat in a hot store room, or a fridge that switched off overnight, can still look perfectly fine and still hand you the wrong number. In Ghana, where daytime heat, humidity and power cuts are all part of the working week, storage needs a little more planning than the box label suggests. Below are seven practical steps that busy hospital, clinic and diagnostic labs use to keep reagents and test strips reliable.

Why storage is harder in Ghana’s climate
Most reagents are validated in air-conditioned labs at 20 to 25 degrees. Many rooms in Ghana sit closer to 30 degrees for long stretches, and the humidity that arrives with the rains pushes moisture into anything that is not sealed. Add the odd power cut and a fridge that quietly warms up while you are not watching, and a reagent can drift out of spec long before its printed expiry date. None of this means you cannot store reagents well here. It just means the usual advice needs a local edit.
1. Know each reagent’s temperature range
Before anything else, read the insert. Some reagents live at 2 to 8 degrees in the fridge, others are happy at room temperature, and a few must never be frozen because freezing breaks them for good. Group your stock by these ranges so nothing ends up in the wrong place. If you remember one rule about how to store lab reagents, make it this one: the fridge is not a default, it is a specific instruction that suits some items and ruins others.
2. Keep test strips away from humidity
Test strips are the most humidity-sensitive items most labs handle. Keep them in their original canister with the desiccant still inside, and close the lid within a few seconds of taking a strip out. Do not decant strips into a separate bottle, do not touch the reaction pads, and never leave the tub open on the bench while you work. A strip that has drawn in moisture can shift a result with no visible change to the pad.
3. Plan for power cuts
A fridge is only as reliable as the power feeding it. Put your reagent fridge on the same backup as your critical equipment where you can, and during an outage keep the door shut so the cold air stays in. A cheap minimum and maximum thermometer inside the fridge tells you whether it drifted overnight, which matters far more than the dial reading when you happen to glance at it. If a fridge has clearly warmed up, check each reagent’s insert before you trust it again.
4. Rotate stock and track expiry dates
Work first in, first out. Put newer stock behind older stock so the older boxes get used first, and write the date you opened a reagent on the label, because many have a shorter life once the seal is broken. A quick monthly scan for items nearing expiry saves you from finding an empty or expired box in the middle of a busy clinic.
5. Keep reagents out of light and heat
Sunlight through a louvre window will cook a reagent left on the sill, and some reagents break down in light even at the right temperature, which is why they come in amber bottles. Keep stock away from windows, away from the back of the fridge motor, and well clear of anything that gives off heat such as an autoclave or a sterilizer. A cool, shaded, stable shelf beats a bright, convenient one every time.
6. Store reagents away from contamination
Keep reagents apart from patient samples, and never store food or drinks in the same fridge. Cap bottles tightly, use a clean tip or pipette each time, and wipe up spills straight away so residue does not build up on the shelves. Cross-contamination is easy to miss and hard to trace once it starts affecting results.
7. Log temperatures and train the team
A simple daily temperature log, signed by whoever checks it, turns storage from a hope into a habit, and it gives you a record if a result is ever questioned. Show every new staff member how to store lab reagents in their first week rather than leaving them to pick it up by guesswork. The World Health Organization publishes clear, free guidance on laboratory quality that is worth sharing with the team (who.int).
Reorder before you run out
Even perfect storage cannot help a reagent you no longer have. Keep a small buffer of your fast-moving items and reorder early, especially before long weekends. Browse our lab reagents and test strips, and our guide to choosing diagnostic test strips, or browse all products, and send your list on WhatsApp to confirm stock and price.

How to store lab reagents: the short version
It comes down to matching each item to the right temperature, keeping moisture and light away, planning for power cuts, rotating stock, and writing things down. Do those well and you waste less, repeat fewer tests, and trust your results more.
